Timothy ★★★★★

Bought these for a jig I was building and the black oxide finish is honestly the standout—no glare under shop lights and they thread in smoothly without any gritty resistance. The full threads grabbed perfectly in the tapped holes, and 600 pieces means I’ll have spares for years.

Adam ★★★★★

The hex socket drive on these 15mm M3 screws fits perfectly with my standard Allen keys, making assembly quick. I've used them for a jig build and the Class 12.9 alloy steel feels seriously tough. For the price, getting 600 of these in one package is a solid value.

Violet ★★★★★

The black oxide finish on these M3 screws gives them a nice, consistent look, and they fit perfectly into my jig's threaded holes without any binding. For the price, getting 600 pieces of this quality for small machinery repairs feels like a steal.
